HCIBK Prolog
NAME : HCPHCIBK
DESCRIPTION: Hardware Console Integration Message Buffer
DSECT : HCIBK
FUNCTION : HCPHCIBK maps the message buffers used to control the
hardware console information to be displayed on the
guest system console (guest's logon terminal).
LOCATED BY : Several queues anchored within the SVPBK contain HCIBK
message buffer blocks:
SVPWBUF field of SVPBK
SVPRBUF field of SVPBK
SVPPBUF field of SVPBK
CREATED BY : HCPPCXIN, HCPPCW76
DELETED BY : HCPPCW77, HCPPCXDL, HCPPCXRS
SERIALIZED : None
